What’s happening in this Kotlin code?

Google Developers (Google I/O) · Jun 29, 2026

A Kotlin coding challenge demonstrates a shared-reference mutation bug when copying a user object.

“They create a new user from an existing one. Then they add a role to the new user. Somehow the original user gains that role, too.”
Frontier results, on device - RL Nabors, Arize

AI Engineer · Jun 29, 2026

Local on-device models can replace frontier models like GPT-5 and Claude to cut inference costs, latency, and security risks.

“Every time you reach for foundation models like GPT-5 or Claude, it's costing you, your users, and the environment.”
The Agentic AI Engineer - Benedikt Sanftl, Mutagent

AI Engineer · Jun 29, 2026

Mutagent proposes an 'Agentic AI engineer' that automates the build-test-deploy-monitor loop for building AI agents at scale.

“the bottleneck basically becomes the human review and the human yeah, building time”
The Prompt is the Platform - Dominik Tornow, Resonate HQ

AI Engineer · Jun 29, 2026

Coding agents will make general-purpose platforms obsolete by generating bespoke implementations from specifications on demand.

“The product is no longer the implementation. The product is the specification, the protocol.”
Quoting Jon Udell

Simon Willison · Jun 28, 2026

Jon Udell argues we should reframe 'human in the loop' as inviting agents into our development loop, not joining theirs.

“I dislike the phrase “human in the loop” because it cedes authority to the machines.”
AI System Design: From Idea to Production - Apoorva Joshi, MongoDB

AI Engineer · Jun 28, 2026

Building production AI systems requires a four-phase framework—requirements, system design, evaluation, optimization—not just vibe coding.

“Specs are the new code. The art is in defining the product requirements, the system design, and evaluate criteria so you can be confident that your AI coding buddies are building the right thing.”
Hack Your Summer

Simon Willison · Jun 28, 2026

Hack Your Summer offers a free 4-week production sprint as an alternative to scarce student internships.

“It's a 4-week, high-velocity production sprint for undergraduate students, graduate students, and recent graduates who want to build something real this summer.”
